Police responded after receiving a report of the stabbing about 3:30 a.m., Vazquez said. The man was taken to Grady Memorial Hospital in critical condition with wounds to the torso and head.

According to police, Riley crossed Peachtree Street and assaulted the man.

Someone observed the attack, and police were able to get a description of a car the attacker used to drive away from the scene.

Investigators determined a car fitting that description was involved in an accident less than a mile away, Atlanta police spokesman Donald Hannah said.
